Monty Don travels across America to uncover what makes its gardens so bold, wild, and surprising. From Missouri’s disappearing prairie and Chicago’s skyline garden to Longwood’s theatrical fountains, New York rooftop farms, Central Park, Bronx community gardens, Long Island landscapes, Chanticleer, and Federal Twist, he explores a country constantly redefining nature. This journey reveals how American gardens mix wilderness, showmanship, reinvention, and personal freedom.
